Question Prongs on wing question

Hope I'm in the right forum for this...

Having sat looking out of the window for hours on planes I have always wondered what the collection of little antenna like things are towards the end and at the back of the wings - there's usually about 5 or 6 of them and they look like little radio aeriels... what do they do?

I think you are talking about the static dishargers, they are protection from lightning strikes allowing an exit from the aircraft of the strike.

A link from BOAC's link,says they are NOT for lightning protection,but merely static electricity. Look here--------------
